  • Publication number: 20130021072
    Abstract: A method and apparatus for controlling the frequency of a clock signal using a clock-gating circuit is disclosed. In one embodiment, a root clock signal and an enable signal are provided to a clock-gating circuit. The clock-gating circuit is configured to provide an operational clock signal (based on the root clock signal) when the enable signal is asserted. The operational clock signal is inhibited when the enable signal is de-asserted. The frequency of the operational clock signal can be output at a reduced frequency (relative to the root clock signal) by asserting the enable signal for one of every N clock cycles. Furthermore, the frequency of the operational clock signal can be dynamically changed by changing the rate of asserting the enable signal relative to the root clock signal, without suspending operation of a functional unit receiving the operational clock signal.

  • Publication number: 20130021353
    Abstract: Techniques and structures relating to virtual graphics processing units (VGPUs) are disclosed. A VGPU may appear to software as an independent hardware GPU. However, two or more VGPUs can be implemented on the same GPU through the use of control structures and by duplicating some (but not all) hardware elements of the GPU. For example, additional registers and storage space may be added in a GPU supporting multiple VGPUs. Different execution priorities may be set for tasks and threads that correspond to the different supported VGPUs. Memory address space for the VGPUs may also be managed, including use of virtual address space for different VGPUs. Halting and resuming execution of different VGPUs may allow for finer-grained execution control, and for better GPU efficiency.

  • Publication number: 20120278557
    Abstract: In one embodiment, a memory that is delineated into transparent and non-transparent portions. The transparent portion may be controlled by a control unit coupled to the memory, along with a corresponding tag memory. The non-transparent portion may be software controlled by directly accessing the non-transparent portion via an input address. In an embodiment, the memory may include a decoder configured to decode the address and select a location in either the transparent or non-transparent portion. Each request may include a non-transparent attribute identifying the request as either transparent or non-transparent. In an embodiment, the size of the transparent portion may be programmable. Based on the non-transparent attribute indicating transparent, the decoder may selectively mask bits of the address based on the size to ensure that the decoder only selects a location in the transparent portion.

  • Publication number: 20120263055
    Abstract: An open-loop fast link adaptation scheme is proposed in an OFDM system. An access point first transmits a downlink packet comprising an open-loop link metric to a wireless station. The open-loop link metric contains a transmit power of the downlink packet plus a receiver sensitivity of the access point. The wireless station measures a received signal strength indication (RSSI) value of the downlink packet. The wireless station then applies open-loop link adaptation and determines a modulation and coding scheme (MCS) based on the open-loop link metric and the RSSI value. The open-loop link adaptation scheme is especially suitable for smart meter/sensor networks as it reduces overhead and increases link capacity.

  • Publication number: 20120211685
    Abstract: A pneumatic actuator air flow control system includes a pneumatic rotary actuator (PRA) and a solenoid air flow control valve (SAFCV). The PRA contains an air reservoir and a vane housing allowing pressurized air to rotate an air-driven vane. The SAFCV includes a flow control valve body (FCVB), a pilot solenoid valve (PSV) and a switch system, wherein the FCVB and the PRA can be connected to direct the pressurized air into the air reservoir, and the PSV is used to control the pressurized air in and out of the PRA to change the vane's rotation movement in the vane housing. Additionally, the switch system allows users to switch between a double-acting and fail-safe operation. When there is no pressurized air and/or electrical power and if an emergent need to open or close the valve, a manual override in the PSV can be used without further installation of a declutchable manual gear operator or external piping when there is no pressurized air and/or electrical power.

  • Patent number: 8248981
    Abstract: The present invention provides a method and system for establishing a highly mobile, long range secure wireless network with dynamic topologies and near full connectivity with acceptable latency using low cost, low power, compact and lightweight devices. One aspect of the system deals with a highly mobile network with dynamic network topologies and a time varying wireless medium that has neither absolute nor readily observable boundaries outside of which radio nodes are known to be unable to receive network frames, although the desirable open field boundary is 1 mile in radius from a base station node. A synchronous frequency hopping technique is used with mobile nodes that can become slave base station nodes to a master base station node to increase the effective range of the master base station without increasing the transmit power.
